  1. How do I setup 2 NIC in WIN10


    I recently purchased a second NIC with a 550 controller chip for 10G access to my NAS.
    I have been having problems getting it set up with a manually assigned IP address as opposed to using DHCP since I do not want my desktop to get confused with routing toward the 10G card. I also eventually want to set up the NAS on a VLAN... but need to do this first.


    When I put in the IP address 192.168.1.11 and subnet mask 255.255.255.000 and the Gateway which is listed on my router xx.xxx.xx.1 and DNS 8.8.8.8 and an alternate DNS 8.8.4.4, Windows 10 says it does not except these?


    I tried using the gateway that the router uses... is the one given by the ISP.. WIN 10 does not let me enter anything saying that there is an error in one of the fields... but it does not indicate which one?

    What could be my problem?

    Any help is appreciated

    :)

    Windows uses wrong NIC in a dual NIC setup, Ignores metric at times.


    Well can I manually force it to not do this or force it to a specific mode? I mean it works fine 90% of the time but then seemingly randomly Windows will just push all traffic that previously went on NIC 1 to NIC 2. So I can use NIC 1 and NIC 2 simultaneously for hours and then suddenly Windows will stop using NIC 1 for all normal traffic and try to use NIC 2 instead, even though my firewall blocks all applications from using NIC 2 (which I think it should realize and start sending the traffic via NIC 1 again)

    It's not actually two different VLANs, it's the same LAN, same subnet. Just that all applications should take NIC 1 to reach it and Tixati NIC 2 to reach it. The routes reflect this by NIC 1 and NIC 2 having the same settings just that NIC 1 has a much lower metric which should mean that Windows should use NIC 1 instead of NIC 2.

    Nothing like that is done with the VPN, the VPN part is working great. The VPN is running on the router and has two connections connections and the router routes traffic from NIC 1 to VPN 1 and NIC 2 to VPN 2, so everything there is working great. The thing that isn't working is the dual connections between router and computer, I don't want Windows to load balance or bridge or fallback, I want Windows to treat them as two different networks of which only one should be used by it which is NIC 1 (But NIC 2 should be enabled and available so that Tixati can force itself to use it)

    Although it sounds like Windows just won't let me set this up? Sounds like it forces what it thinks is best for my system even if it isn't? I guess I'll just have to disable/enable NIC 1 every time it happens then.

    Thanks for answering. =)

    Regardless how you have it set up on the Router. Windows will naturally Load Balance, bridge or do a fall over.

    Having both NIC's hooked up to two different VLAN's, makes the computer the host for handling all connections from one VLAN to the other.

    I would suggest only using one NIC at a time, and if you need the other, then enable it when you need it.

    Trying to reinvent the wheel and do something that is not done with a VPN, is just going to keep causing you headaches.

    Normally the setup you have is done for Labs or Domains, not every day use.

    How do I setup 2 NIC in WIN10

    Local account - as before - disconnect NIC cable

    Hi there

    as before (Win 8 / 8.1) if you want a LOCAL account simply during the setup phase just disconnect the NIC cable (or if on a VM detach the virtual NIC. Then go back a step and it will then prompt you for a local user.

    Surprised nobody has mentioned this yet.

    Cheers
